1'0 11]/ 1127111111 1'/ 1111/1/ Wonne/'11 Be it l nown that l, A. A. lEA'Vl, of ('lreenfield, in the eounty ot Franklin and State of Massaehusetts, have invented a new and linproved Shaekle for Connecting 'lhills to Axles; and I do hereby declare that the t'ollow ing,` is a full, elear, and exact deseription ot' the same, ret'erenee being had to the aeeotnpanying drawings, mak ingI a part ol' this speeil tleat'ion, in whiehq VFigure lV is aside view ol my invention; Yliig. 2, a plan or top view ol the same; Fig. El, a seetiou ot' the saine, taken in the line .1' .11', Fig. l.

Similar letters otl reiterenee indieate eorresponding' parts ill the several Heures.

rlhe object of this invention is to obtain a sliaefkle or tliill-eoupling' whieh will be simple in eonstruetion, forni a strong and durable eonneetion, and in ease ot' breakage possess in itself a means to vli'orm a temporary etimneetion to prevent the detiaehinent of the tihills t'roin the axle, so as to avoid the applieation or use ot' the ordinary safety-straps" now employed to prevent the thills, in ease oll sueh a Contingency, eenling in Contact with the heels ofi' the horse and frighteniiiig' the same.

The invention consists in havingl the back ends ol the irons ol. the thills bent in hook torni, fitted in eyes whieh are at-taehed to the axle, and secured therein by Center bolts and nuts or an equivalent means, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and eonstruet my invention, l will proceed to describe it.

A represents the iron ot' a thill, which is ot 4 Curved form and seeured to the baek end 0l the thill b v bolts, as usual. The lower end made a eonieal reeess, c1, as shown in Fig'. a,

ol this iron is bent intthe Forni of a hook, as shown aty ll in Fig. l, and the portion of the iron j ust above the hook is enlarged, as shown by the dotted lines in Fig. l. ln eaeh side ot' this enlarged portion oli the iron A there is to reeei ve the eoniea-l or pointed ends of two ierews or bolts, (l (l, tvhieh pass laterally through the sides ot' an (-1ve,l),attaehed to the axle.

The hook ll ol the iron is below the eye l), as shown in Fig. l, and the bolts (l are firmly seeured in the eye byineaus et nntsbb,whieh are screwed up againstt-he outer sides of the eye, as shown elearl)7 in lfig. il.

The bolts (l, it will be seen, seeure the iron A in the eye fl) and at` the same time admit ol' the iron playing' or worl'iuf.;l on the bolts under the motion oli the thills. ln ease ot? wearthe bolt-s t may beserewed up, so asto elteetually prevent. any ratttvlingot the iron in the eye. lt either or both of thebolts should `give way or break, the hook ,B will eateh on the t'ront part ol the eye, as shown in red in Fig'. l, and prevent the lLhill being, detaehed from the axle. Thus the safety-straps are avoided. The devieeis extremely simple and may be eonstrueted at a small cost'.

llaving thus described my invention, what l elaim as new, and desire to seen re by Letters,
